The engine and the toeboard cross member partly overlap in a projected plane along a fore-and-aft direction to provide a space behind the control unit in a front view of the vehicle. The intake manifold and the control unit are disposed within a contour of the engine in a plan view of the vehicle. The intake manifold is disposed ahead of the control unit, and portions of intake pipes of the intake manifold on both sides extend rearward and are partly opposed to both side surfaces of the control unit.

A drive train (1) for a motor vehicle (100) has an electric machine (2) with a rotor (3), a stator (4) and an air gap (5) between the rotor (3) and the stator (4). The drive train (1) also has a transmission (6) and a cooling circuit (7) for conducting a coolant through the electric machine (2) and the transmission (6). The coolant is provided for lubricating and cooling the transmission (6) and for directly cooling electrical conductors of the stator (4). The cooling circuit (7) is provided in such a way that the coolant does not enter the air gap (5).

A vehicle includes a battery, an inverter, a permanent magnet electric machine, and a controller. The controller commands discharge of a storage element of the inverter through the permanent magnet electric machine via a current having a zero quadrature axis component and a positive direct axis component.

A rotating electrical machine and an input member are placed on a first axis, a counter gear mechanism is placed on a second axis, and a differential gear mechanism is placed on a third axis. The input member, the counter gear mechanism, and the differential gear mechanism have portions placed on an axial first side with respect to the rotating electrical machine. A pump portion is placed on the opposite side of an imaginary plane passing through the first axis and the third axis from the second axis, and is placed at a location that overlaps at least one of the rotating electrical machine and the differential gear mechanism in an axial view. The pump portion is placed on the axial first side with respect to the rotating electrical machine.

An accessory component assembly is provided that includes a frame, a first vehicle accessory, and a second vehicle accessory. The frame is configured to support vehicle accessories. The first vehicle accessory is mounted to the frame. The second vehicle accessory is mounted to the frame. The frame is configured to simultaneously couple the first vehicle accessory and the second vehicle accessory to a chassis of a vehicle such that the accessory component assembly can be functionally coupled to at least two other vehicle sub-systems.

A drive apparatus includes a motor; a reduction gear connected to the motor; a differential connected to the reduction gear, for rotating an axle about a differential axis; a housing including a gear housing portion housing the reduction gear and the differential; and an oil housed in the gear housing portion. The differential includes a gear for rotating about the differential axis. An end portion of the gear is lower than the reduction gear, and is configured to soak in the oil. The housing includes an oil drain hole and an oil feed hole for joining an interior of the housing and a space outside of the housing, a first stopper member removably in the oil drain hole, and a second stopper member removably in the oil feed hole. Each of the oil drain hole and the oil feed hole is in a portion of the gear housing portion.

A vehicle includes: an electronic device accommodated in an accommodation case of a power storage device; and a signal wiring connected to an electronic device and an in-vehicle device, the signal wiring being a signal wiring in which a signal to be received or transmitted by the electronic device or the in-vehicle device travels. An exhaust pipe is disposed at a position adjacent to a first side surface, and the signal wiring is drawn out from the second side surface to outside of the accommodation case.

A power conversion device includes a main battery, an auxiliary battery, an inverter circuit, a high-voltage wiring, a smoothing capacitor, a main wiring, a subsidiary wiring, a DC-DC converter and a controller. The DC-DC converter is connected to a high-potential wire of the main wiring, a low-potential wire of the main wiring, a high-potential wire of the subsidiary wiring, a low-potential wire of the subsidiary wiring, the high-potential wire of the high-voltage wiring and the low-potential wire of the high-voltage wiring. The controller is connected to the auxiliary battery and the DC-DC converter. The DC-DC converter is configured to supply a power stored in the smoothing capacitor to the controller through the DC-DC converter such that the controller drives the inverter circuit and that the power stored in the smoothing capacitor is supplied to the motor through the inverter circuit, when a collision of the vehicle is detected.
